latte-integrale

Software for counting lattice points/integration over convex polytopes

LattE (Lattice point Enumeration) is a computer software dedicated to the problems of counting lattice points and integration inside convex polytopes. LattE contains the first ever implementation of Barvinok's algorithm. The LattE macchiato version (by M. Koppe) incorporated fundamental improvements and speedups. LattE integrale, the latest version, has the ability to directly compute integrals of polynomial functions over polytopes and in particular to do exact volume computations. Version 1.6 adds the capability of computing the highest coefficients of weighted Ehrhart quasipolynomials.
